These Press Force load cells are based on the piezoelectric measuring principle. The force acting on the quartz element generates at the output of the sensor a proportional electric charge, which is converted by the series-connected measuring amplifier into a process signal suitable for evaluation (typically 0 … 10 V). Depending on the type of sensor, tension forces of up to 16 % of the compression force range can also be measured. Although uncalibrated, these ranges are often used for detecting tool withdrawal forces, for example after press-fit processes.

They come in five different sizes which are divided in seven measuring ranges.
